Y AXLEJJOINT. Y

This invention relates to axleA jointsv and consists in certain improvements inthe construction thereof as will be hereinafter fully described and pointed outin the claim.

.Axle joints of various types are 'subjected to great strains and by reason of this Vit isV usual to form such ointsv with a yoke having the-arms extend each side of the companion member. There this is done it is either'n'ecessary to machine the surfaces in contact in the inner faces of the arms ofthe yoke Aor it is necessary to make the distance between when finished.

The obj ect of the invention is to providera simple means for forming such an axle joint in which the forming accurately the inner surface 0f the arms a pre-determined `distance apart is obviated.` Y I y In the drawings, Figure lis an elevation of the device certain parts being in section; and Fig. 2 is a section'on line 2 2 of Fig. 1.

T he invention is illustrated in the accompanying drawings wherein- 1 marks the axle, 2 the wheels on the axle, 3 a platform or bolster, 4: a king post and' 5 a oint yoke at the bOttom of the king post, the yoke having the arms 6 and 7.l

The arm 6 has a'perforation 8v and the arm 7 the perforation 9, the perforation 9 being somewhat larger than the perforation 8. The axle 1 has a perforation 10 preferably of thc` same size as the perforation 8. The bolt 1 1 Copies of this patent may be obtained for Specification of Letterslatent. I

axle. Preferably it is so'shaped and of such` Y a sizeas to form a joint in the perforation 9. Vf ith this construction a joint be f formed by means of which the axle may be held in contact with one of the arms of the yoke. This is done `by drawing up the bolt 11 by means ofthe nut 13 until the axle is just in Contact but free to *move inthe joint.

'The'liead 12 makes a complete supportfor the head Vend of the bolt. It will be readily fectly tight joint may be secured.

I/Vhat I Vclaim as new is In an axle joint,VV the combination-'of the axle;` a king post having a yoke in its lower Y lseen that the inner surfaces of the arms 6 and 7 do not require machining or finishing `to make a close itwith the axle-yeta 'pen foration in the axle; a bolt having its head disposed in theY larger perforation and against the axle, said bolt extending through the perforation in the axleand into the per-` foration in the other arm ofthe yoke; and` means for securing thebolt in place.

In testimony whereof I have hereunto set my hand in the presence of two subscribing f witnesses. j
